Diagnostics and error tracing

The GESRTP Communication Driver uses the standard diagnostic information provided by the Operations Integration Toolkit. Access to other internal diagnostic registers of the PLC is performed through reads and writes via the syntax used in item naming.

The GESRTP Communication Driver supports error messages, controller-specific error messages, and error codes. Use the Log Flag data to customize the type of messages logged to the Log Viewer.

Note: See the Log Viewer Help for more information about using log flags.

GESRTP Communication Driver Log Flags

The GESRTP Communication Driver supports the following server-specific log flags.

• Errors
  General errors from the Communication Driver have the prefix "ERROR." They are highlighted in red so that you can find them quickly. Log flags for GESRTP-specific errors have the suffix "_ERROR." They include CONNECTION_ERROR, POLL_ERROR, and POKE_ERROR.

• Trace
  General traces from the Communication Driver have the suffix "_TRACE." The sever-specific trace log flags include CONNECTION_TRACE, POLL_TRACE, and POKE_TRACE.
